@Gambino -
I wouldn't be so hard headed over the contacting her concern. If she is truly interested then it won't matter. The girls you have to play games with to attract/re-attract aren't worth it anyways.
I'd take my time and be patient. Make sure this is what you want. A LTR will likely be the only card on the table in this situation. If you start seeing her again, I would be skeptical and just take it day by day.
I've had these deals go 2 ways.
A. Start seeing each other again and its only about sex & friendship. Eventually she says no more and/or you find some other girl.
B. You make an effort to resolve the problems that created the divide, yet things never get back to how they were before and the relationship comes to an end again.
Sometimes a guy has to ask himself..........If I was banging some other girl that was hot, sweet, submissive, fuhked, like a p0rnstar, etc would I be interested in seeing my exgf still? If you haven't banged anything else since her and you still miss her somewhat, is this just horniness and old emotions talking or is this something pure and deep?
I wish it wasn't true, but its almost always best to move on and find somebody new. But I wouldn't know this if I'd of never went back to several exes and figured this out. ;-) So there is value to be had from such things. Never hurts to try something again so you know for sure.
All we can do is better realize what you want and need, and learn from our past.
